Specific embodiment
It is further discussed below the present invention with reference to embodiment.Embodiment does not limit the claim of the present invention.
The pipeline rehabilitation tubulose ramie/terylene composite material for weaving of invention design, by the non-woven internal lining pipe of terylene and washing
It is mixed into ramee and ramie yarn and thread respectively, the no-dig technique for the buried damaged pipe in city is repaiied in the material of the woven internal lining pipe of synthetic fibre
Again it is characterised in that its pipeline rehabilitation composite is all that natural fiber ramie is mixed manufacture with polyster fibre.This mixing
The non-woven fabric of natural ramie and woven fabric have more preferable resin impregnated performance than pure terylene non-woven fabric and woven fabric, in reality
More resins and tube wall can be carried in the construction of border to bond, reduce inner-walls of duct and subside the possibility of generation.And add ramie
Fiber, cost-effective, environmental protection.
The present invention devise simultaneously pipeline rehabilitation tubulose ramie/terylene mix non-woven composite and tubulose ramie/
Terylene is combined the manufacture method (abbreviation manufacture method) of woven composite material both, and this manufacture method is applied to the pipe of the present invention
Road is repaired tubulose ramie/terylene and is mixed nonwoven fabric composite and the compound woven composite material of tubulose ramie/terylene, including following
Technique：
Tubulose ramie/terylene non-woven composite：
1. that designs ramee mixes ratio：The tensile strength of actual ramie/terylene hybrid composite is fine with ramie
The volume content of dimension is linear, and that is, the tensile strength of this non-woven composite is with the increase of ramee volume content
And reduce.But non-woven material also can be made to have more preferable resin impregnated performance, contain when ramee volume content accounts for total fiber
When amount reaches critical hybrid ratio, the tensile strength of hybrid composite reduces speed and can change therewith, according to engineering practice
Require with material cost, draw optimal hybrid ratio of hybrid fiber composite.Therefore design ramee be mixed in ratio for 0.1-0.3.
2. design fleece is quantitative：Starting web is quantitative bigger, and quantitative decrement caused by non-weaving cloth processing is got over
Few, pricker passes through the coverage of fibre web just big, and the entanglement of fiber and compacting degree are just high, the initial elasticity of needle fabric
Modulus is just high, and extension at break and fracture strength are bigger, but when fibre web quantitatively reaches certain value, the fracture of non-weaving cloth is strong
Degree can reach a peak value and then certain decline occurs, this mainly due to the excessive puncture of fiber make fiber disconnected
Split that ratio is more serious, lead to the strength of non-weaving cloth to decline.Therefore design the quantification of 100g/m of fleece here21000g/m2.
3. the needling density in design nonwovens process：Needling density is important technological parameter in non-weaving process, its meeting
Direct role and influence are produced to structural parameters, mechanical property and the non-quality being made into product.Therefore design design here is non-knits
Making the needling density in technique is 60 thorns/cm2600 thorns/cm2.
4. be obtained non-woven fabric reserve joining edge coating antiseepage film after be stitched into tubing, suture mends even coating
Layer, you can described tubulose ramie/terylene non-woven composite is obtained.
Tubulose ramie/terylene woven composite material：
1. design the mixed proportion of ramie yarn and thread in weft yarn：Reality is because the coarse surface of ramee and ramee bundle
Between larger space make the impregnability of resin be better than terylene, in weft yarn, the mixed impregnability than bigger textile resins of ramie yarn and thread is more
Good, but fabric count is all affected by the mixed ratio of ramie to tensile strength and elongation at break, and initial ramie mixes stronger than bigger fabric
Degree is lower, and elasticity is poorer, makes ramie mix the ratio intensity must being fulfilled for woven liner composite material and aeroelastic requirements, therefore designs latitude
In yarn, the mixed ratio of ramie is 0.1-0.5.
2. woven fabric filling yarn fineness：The fineness of yarn directly determines the thickness of fabric and then impact tubular textile is combined
The thickness of material, fabric thickness can be similar to filling yarn diameter sum.Spin according to tubulose taking the gas pipeline of 500mm as a example
The requirement of Woven composite thickness, can probably predict fineness of yarn, typically require the denier of yarn 3000 denier -10000 denier it
Between.
3. woven fabric is through latitudinal density：The density of tubing directly affects the tensile property of tubing, and to rear
Continuous press mold and impregnating resin also have a certain impact.For example density is little, and fabric is lax, and during press mold, antiseepage film is easily impregnated into fabric
Another side, makes finished product endure with all one's will.If Density is too big, resinoid bond impregnation difficulties, fabric carries resin-bonded dosage not
Foot, the bonding of impact resin and tube wall.Therefore, should be according to the fineness of selected yarn, the strict density controlling fabric, weft density
Control in 30-80 root/10cm.
4. the tubular woven coating antiseepage film being obtained, you can described tubulose ramie/terylene woven composite material is obtained.
